Abstract

UN SISTEMA DE PROTECCION DE PASAJEROS QUE INCLUYE UN SENSOR DE CHOQUE PARA DESPLEGAR UN AIRBAG DE UN VEHICULO EN SITUACION DE CHOQUE. EL SENSOR DE CHOQUE INCLUYE UN CIRCUITO ACELERADOR DE BAJA FRECUENCIA Y UN CIRCUITO TRANSDUCTOR DE PRESION DE ALTA FRECUENCIA. EL CIRCUITO ACELERADOR DE BAJA FRECUENCIA ES SENSIBLE A LAS SEÑALES DE BAJA FRECUENCIA PROVINIENTES DE LA DECELERACION DEL VEHICULO COMO RESULTADO DEL CHOQUE, Y EL CIRCUITO TRANSDUCTOR DE ALTA FRECUENCIA ES SENSIBLE A LAS SEÑALES DE ALTA FRECUENCIA PROVENIENTES DE LA DEFORMACION DE LOS COMPONENTES METALICOS COMO RESULTADO DEL CHOQUE. LA COMBINACION DE LAS SEÑALES DE BAJA Y ALTA FRECUENCIA PROPORCIONA UNA INDICACION PRECISA PARA EL ACCIONAMIENTO DEL AIRBAG.
